HESI Fundamentals Practice Questions
1. A healthcare professional is preparing to administer lactated Ringer's (LR) IV 100 mL over 15 min. How many mL/hr should the IV infusion pump be set to deliver? (Round the answer to the nearest whole number. Do not use a trailing zero.)
- A. 400 mL/hr
- B. 200 mL/hr
- C. 300 mL/hr
- D. 250 mL/hr
Correct answer: A
Rationale: To administer 100 mL over 15 min, the IV pump should be set to deliver 400 mL/hr. This calculation is based on the concept that if 100 mL is given in 15 minutes, to find out how many milliliters are given in an hour, you would multiply by 4 (since 15 minutes is a quarter of an hour). Therefore, 100 mL x 4 = 400 mL per hour. Choices B, C, and D are incorrect as they do not reflect the correct calculation for the infusion rate required to administer 100 mL over 15 minutes.
2. A nurse is caring for a client who has a new prescription for tube feeding. The nurse understands that the provider prescribed tube feeding because the client:
- A. Is unable to swallow foods by mouth
- B. Has a gastrointestinal obstruction
- C. Requires additional caloric intake to support healing
- D. Is at risk for aspiration
Correct answer: A
Rationale: The correct answer is A: 'Is unable to swallow foods by mouth.' Tube feeding is prescribed when a client is unable to safely swallow food by mouth but has a functional gastrointestinal tract. Option B, 'Has a gastrointestinal obstruction,' is incorrect as tube feeding is not typically prescribed for this reason. Option C, 'Requires additional caloric intake to support healing,' is incorrect because tube feeding is specifically for clients who are unable to swallow. Option D, 'Is at risk for aspiration,' is also incorrect as tube feeding would not be the primary intervention for aspiration risk; other strategies to reduce aspiration risk would be implemented instead.
3. A client is evaluated by a nurse regarding the use of a sequential compression device. Which of the following client statements indicates understanding of the device's purpose?
- A. “This device will keep me from developing skin sores.”
- B. “This device will keep the blood circulating in my leg.”
- C. “This device will prevent my leg muscles from weakening.”
- D. “This device will maintain the health of my joints.”
Correct answer: B
Rationale: The correct answer is B because sequential compression devices are utilized to enhance circulation and prevent clot formation in the legs. Option A is incorrect because these devices are not primarily meant to prevent skin sores. Option C is incorrect because the devices do not directly address muscle weakness. Option D is incorrect as the main purpose of sequential compression devices is not related to joint health.
4. A client in a provider’s office tells the nurse that, 'I fast for several days each week to help control my weight.' The client takes several medications for various chronic issues. The nurse should explain to the client that which of the following mechanisms that result from fasting puts her at risk for medication toxicity?
- A. Increasing the metabolism of the medications over time
- B. Increasing the protein-binding response
- C. Increasing medications’ transit time through the intestines
- D. Decreasing the excretion of medications
Correct answer: B
Rationale: Fasting can lead to an increased protein-binding response of medications. This can result in a higher concentration of bound medications in the bloodstream, potentially causing toxicity as the medications may not be readily available for metabolism or excretion. Choice A is incorrect because fasting typically doesn't increase medication metabolism. Choice C is incorrect as fasting usually decreases transit time through the intestines. Choice D is incorrect since fasting generally does not decrease medication excretion.
5. A client with a history of deep vein thrombosis (DVT) is admitted with swelling and pain in the left leg. What is the most appropriate action for the LPN/LVN to take?
- A. Apply warm compresses to the affected leg.
- B. Elevate the left leg above the level of the heart.
- C. Measure the circumference of the left leg.
- D. Administer pain medication as prescribed.
Correct answer: C
Rationale: Measuring the circumference of the left leg is the most appropriate action for an LPN/LVN when assessing a client with a history of DVT and presenting with swelling and pain in the left leg. This measurement helps to assess the extent of swelling objectively and monitor changes in the client's condition. Applying warm compresses (Choice A) may worsen the condition by potentially promoting clot development. Elevating the left leg above the level of the heart (Choice B) is generally recommended for DVT to improve venous return, but measuring the circumference is more appropriate in this scenario. Administering pain medication (Choice D) does not address the underlying issue and should not be the initial action taken.
